There is no 10x1.0mm because I made that up. I don’t use the Hornady/Stony point tool.
No shit?I've used the 5/16"X36 TPI for this operation, an extra fine thread. I haven't heard of using a 10X1.0MM for this. Depending on how much jump you have, the bullet configuation you select will determine the coal length to hit the lands, or back off what you want. Berger, with their long taper is often not able to hit anywhere near the lands, without having no bullet left in the neck. It may also not fit your magazine either. I have switched to Sierra instead of Berger in a 22-250 that was chambered by JD Jones. It is 1 turn in 7 and supposed to have a throat of the proper length to accept long bullets. I was unhappy with the throat length, but I was stuck with it. Bergers were up to 1/8" off lands when seated 1/8" into the neck, while with Sierra Matchkings, the coal was shorter, had about 1/8" for seating and was .020" off lands. Try "Drills and Cutters" website for taps, dies and correct drills.
